Marlin renderer should not be the default in 8u252

Steps to reproduce:
- Build jdk8u from http://hg.openjdk.java.net/jdk8u/jdk8u repository
- compile SimpleImage.java app:
-------------- SimpleImage.java ---------
import javax.imageio.ImageIO;
import javax.swing.*;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;

public class SimpleImage {

    public static void main(String[] args) throws Exception {
        JLabel label = new JLabel("Hello, world");
        label.setSize(200, 100);
        BufferedImage buff = new BufferedImage(200, 100, BufferedImage.TYPE_INT_RGB);
        Graphics g = buff.createGraphics();
        g.setColor(Color.WHITE);
        g.fillRect(0, 0, 200, 100);
        label.print(g);
        g.dispose();

        ImageIO.write(buff, "png", new File("hello.png"));
    }
}

Run the app with sun.java2d.renderer.log=true java property:
java -Dsun.java2d.renderer.log=true SimpleImage
